Questions and Answers

Extensive vehicle deformation in a car accident increases the likelihood of injuries to passengers

False

What material property allows car parts to crumple and absorb impact energy during a collision?

  • Brittleness
  • Elasticity
  • Plasticity (correct)
  • Malleability
  • What is the primary purpose of frontal crumple zones?

  • Increase the kinetic energy of impact
  • Decrease the time of impact, and thus increase the force experienced by occupants
